[Answered] Consider the following grid of integer points in the plane: P_{ij} = (i, j), 0 ≤ i, j ≤ 4. We wish to represent this grid of points as a list of tuples. The name of the list should be 'points'. Each element of the list should be a tuple of the form (x, y). The first element of the tuple is the x-coordinate (horizontal) of the point, the second is the y-coordinate (vertical). We have employed the standard Cartesian coordinate system. Select all the correct implementations of this program. (MSQ) 1. points = [] for x in range(0, 5): for y in range(0, 5): (x, y) 2. points = [] for x in range(0, 5): for y in range(0, 5): ([x, y]) 3. points = () for x in range(0, 5): for y in range(0, 5): ((x, y)) 4. points = [] for x in range(0, 5): for y in range(0, 5): ((x, y))
